Ok.
I can easily to change this.
How would you prefer the iscsi:// url look like ?

You cant yet. :-(

Right now they are hardcoded to reasonable defaults I think will work
for most targets.
I want to add more of these features and make them settable from the
command line,
but that will take a lot of time.

Hopefully having a basic/non-flexible implementation as a first step
may even encourage others to
contribute to improve it until it is full featured.
